Maintaining the 2017 Subaru Outback with a consistent oil change schedule is fundamental to ensuring its renowned longevity and performance. This specific model, a blend of a rugged crossover and a refined sedan, relies on the proper lubrication of its horizontally-opposed "flat" engine to handle its unique driving dynamics. Using the correct oil, whether conventional or synthetic, and adhering to the Subaru-recommended intervals protects the intricate machinery beneath the symmetrical all-wheel-drive system. Neglecting this basic care can lead to increased friction, reduced fuel economy, and potential long-term damage to critical components that define the Outback's capability.
Understanding the 2017 Outback's Engine Requirements
The heart of the 2017 model year is the 2.5-liter FB25 Boxer engine, a design that benefits greatly from regular oil changes due to its flat layout. Unlike a traditional V-shaped engine, the boxer design places the cylinders horizontally on either side, which means oil pools differently and circulation is a key factor in preventing wear. For the 2017 model, Subaru specified 0W-20 synthetic oil for most trims, a lightweight formula designed to maximize fuel efficiency and ensure quick lubrication during cold starts. Using anything thicker than the recommended viscosity can strain the engine and reduce the fuel economy that the CVT transmission aims to provide.
Oil Type and Capacity Specifications
When performing a 2017 Subaru Outback oil change, selecting the correct oil filter and capacity is essential for the system to function correctly. The engine holds approximately 4.5 to 5.3 quarts of oil, depending on the specific trim and whether the oil filter was replaced. It is critical to use a high-quality filter that meets Subaru's standards, as a poor filter can allow contaminants to bypass the bypass valve and circulate through the engine. Always refer to the owner's manual for the exact oil weight (0W-20 is standard) and capacity to avoid underfilling or overfilling, both of which can cause significant mechanical issues.
The Importance of Adhering to Intervals
Subaru recommends an oil change interval of 6,000 miles or 6 months, whichever comes first, for the 2017 Outback. This schedule is designed to account not just on mileage, but also on the degradation of oil quality over time due to moisture and heat. Even if the vehicle sits in the garage for weeks or months, the oil can break down and accumulate moisture, which compromises its protective properties. Sticking to this timeline ensures that the engine remains protected during those long stretches of highway driving and daily commuting, preserving the robust nature of the Subaru boxer engine.
Step-by-Step Change Procedure Highlights
Warm up the engine for a few minutes to loosen the oil viscosity, then turn it off and lift the vehicle safely on jack stands.
Locate the drain plug underneath the oil pan and place a catch pan, removing the plug carefully to control the flow of used oil.
Replace the oil filter with a new Subaru-recommended part, applying a small amount of fresh oil to the gasket to ensure a proper seal without over-tightening.
Pour the new 0W-20 oil through the filler cap, checking the dipstick incrementally to reach the correct level without exceeding the maximum mark.
Check for leaks underneath the vehicle after starting the engine and taking it for a brief test drive to circulate the new oil.
